Annual Cycle: Parrot feather is an aquatic perennial that propagates through root division and plant fragments. After treatment with a suspension of the bacterium all parrot’s feather sections above the water died. Chemical Parrot feather’s waxy cuticle on stems and leaves can only be penetrated with a wetting agent, making chemical control challenging—the weight of spraying may cause the plants to sink in the water, which can wash the herbicide off before it can take effect. South African Journal of Science 73:89-90. Myriophyllum aquaticum has expanded its range mainly in the southern United States and may be relatively innocuous in the northeast due to a smaller number of occurrences (Hoyer et al. Mechanical methods are much less documented; however, their use may facilitate regrowth and further spread of parrot feather. some of you may have already seen/read this before but I thought it was worth posting Plant Protection Quarterly 17:27-34.] Aquatic Vegetation Management Plan 2008-2012: Meserve Lake, Steuben County. Dispose of them in the garbage or away from any waterbody. Parrot feather is not seriously affected by frost (Moreira et al. The list of references for all nonindigenous occurrences of Myriophyllum aquaticum are found here. However, an inverse relationship existed between M. aquaticum yield and tissue phosphorus content. Cardwell et al. I’m trying to find out if parrots feather is a good plant for my ducks and geese to eat. Parrot feather can survive winters in its submersed form and begin growth when water temperatures reach 7°C (Moreira et al. 2007). Parrots feather has both submerged and emergent leaves that grow above the surface of the water. Floating mats of M. aquaticum have been measured at up to 26 kg of fresh weight in Europe and are capable of reducing the oxygen content of the water below to <1 mg O2L-1, which can be detrimental to fish (Fonseca 1984 cited in Moreira et al. 2009. 1999) reported that parrot’s feather Myriophyllum aquaticum plants treated with a strain of the bacterium Xanthomonas campestris did not die. 2009b. Chapter 19a In: A.H. Pieterse and K.J. Getsinger. 2006. Available http://www.issg.org/database/species/ecology.asp?si=401&fr=1&sts=sss&lang=EN. Anderson. It prefers a warmer climate, it is chiefly found in southern parts of the U.S. Parrot feathers are a fresh water plant , it can be found in lakes, ponds, and streams. Journal of Aquatic Plant Management 44:13-18. (1998) reported that parrot feather was tolerant to mechanical disturbance (raking and chaining) and the repeated application of mechanical techniques favored parrot feather dominance in canals. 2009a, Rixon et al. 2008. (2011) compared Belgian lake sites that were heavily invaded (90-100% cover), semi-invaded (~25% cover), and uninvaded by M. aquaticum and found that native species richness was 57% lower in heavily invaded sites relative to uninvaded sites. Myriophyllum aquaticum was first reported in the southern New England region (southeastern New York) in 1929 (Couch and Nelson 1985b). Myriophyllum aquaticum is a hardy species with broad environmental tolerances (see Ecology above). Les, D.H., and L.J. The South and Central American native came to the country in the 1800’s to decorate indoor and outdoor aquariums. If you are not happy i will refund but item must be returned to me and you have to pay the postage back . 2008). 27 January 2011. http://www.issg.org/database/. This information is preliminary or provisional and is subject to revision. However, after six weeks new shoots developed from the submerged stems leading to plant recovery. Center for Aquatic and Invasive Plants, University of Florida, IFAS. Polomski, R.F., M.D. While this suggests that M. aquaticum could be used as an important indicator species (see below), the consumption of M. aquaticum by grazers could increase the bioaccumulation of heavy metals in the food web. McMillan, and J.D. 1999) and is established in Germany (1988) but still considered rare (Hussner et al. It can also survive frequent inundation of salt water as long as concentrations remain below 4 ppt (Sutton 1985). Dugdale. Vancouver, B.C. Plants and floating mats of vegetation are sometimes uprooted, choking waterways, inhibiting navigation, and potentially blocking pumps or drainage (Engineer Research and Development Center 2007, Sheppard et al. Submerged leaves are 1.5 to 3.5 cm long and emergent leaves are 2 to 5 cm long and much greener. 5 Other Reasons Your Parrot Could Be Feather Plucking. Journal of Chemical Ecology 25(1): 209-220. Aquatic Weeds, 2nd Edition. Sebbatini et al. Parrotfeather growth can inhibit the growth of more desirable plant species such as pondweeds and coontail (Ferreira and Moreira 1994), which are readily utilized by waterfowl as food items (Wersal et al. Westerdahl, H.E. 1985. Biology and ecology of Myriophyllum aquaticum. 2005). 2010. Dense growth can also diminish the recreational value and seriously affect the perceived aesthetic qualities of infested waterways (Banfield 2008, Washington State Department of Ecology 2011). Birds are free to fly and they represent freedom, and birds are extremely spiritual animals. Ultimately, to prevent the future introduction and spread of parrot feather into new areas it must be prohibited from sale by the water garden and aquaculture industries. Feather plucking is a problem of captivity. Sabbatini, J.H. Madsen. Mabulu, L.Y. Staminate (male) plants are rare even in native populations of South America (Orchard 1981). Proceeding, 1st International Symposium on watermilfoil (Myriophyllum spicatum) and Related Haloragaceae Species. Dense infestations of parrot feather can rapidly overtake small ponds and sloughs, changing their physical and chemical properties, including impeding water flow, which can result in increased flood duration and intensity. 2000, Nwoko 2010). http://plants.usda.gov/java/nameSearch. Herbicide trials for the control of parrotsfeather. Nitrogen and phosphorus remediation by three floating aquatic macrophytes in greenhouse-based laboratory-scale subsurface constructed wetlands. ), Myriophyllum brasiliense (Camb. Couch. Wersal and Madsen (2011) proposed that high levels of phosphorus favored the growth of algae (superior competitors in phosphorus uptake) causing shading in the water column and suppressing the growth of M. aquaticum (Wersal and Madsen 2011).
